DRAIN-PIPE CONNECTION'AND PLUG FOR BATHS, 80C.

SPECIFICATION forming part of Letters Patent No. 247,273, dated September 20, 1881.

Application filed July 15, 1881.

To all whom it may concern:

Beitknown that I,WILLIAM RIoKET'rs, a citizen of the United States of America, residin g at Oincinnati,in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Drain-Pipe Connections and Plugs for Baths, &c.; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

Heretofore it has been customary in applying the plug-seat and joining the drain-pipe to lined baths, sinks, &c., to insert the plug-seat in the lead drain-pipe, and to then solder the pipe and plug-seat to the countersunk lining, leaving the solder exposed. This is objectionable, because it is difficult, by reason of the bulging of the lining'and difficulty of dressing, to make a nicely-finished joint or connection in that way, and also because the plug-seat cannot be removed without unsoldering.

The object of my invention is to so join the drain-pipe to the bath or sink and so construct and apply the plug-seat that the lining shall be prevented from bulging in the act of soldering, the solder shall be covered by the plugseat, and the plug-seat shall be removable without the necessity of disturbing the joint.

To this end my invention consists of certain combinations of devices, which combinations are specifically stated in the claims atthe close of this specification.

In order that my invention may be clearly understood I have illustrated in the annexed drawings, and will proceed to describe, the best form thereof at present known to me.

Figure 1 is an axial section, showing my invention applied to the bottom of a bath-tub. Fig. 2 is a horizontal section in the plane indicated by the broken line so a; of Fig. 1.

The same letters of reference indicate like parts in all the figures.

A refers to the wooden bottom of a bath, and a to the tinned copper lining thereof. As usual, a countersink is formed around the drain-pipe hole. This hole is made somewhat (No model.)

larger than the lead drain-pipe B, in order that a thimble, G, preferably of. brass, may be passed through the hole around the upperend of the drain-pipe.

The thiinble is provided with a flange, '0, at its upper end, suitably beveled .on its under side to fit the slant of the countersink. The lower end of the thimble passes through the bottom of the bath, and, being externally screw-threaded, receives a nut, C, by'means of which it is to be drawn downward to cause its flange c to firmly press the lining a down on the bottom A, and thus prevent it from bulging under the heat of the solder to be applied, as will be presently explained. The thimble may also be provided with a fine internal screw-thread, for embedding itself in the lead drain-pipe on inserting the same,and

thus support it while the joint is being completed.

The upper end of the drain-pipe should project a little above the adjacent surface of the flange c, and this projecting end may be expanded over such flange, though that is not essential. The upper end of the drain-pipe and the flange 0 must be some distance below the level of the flat portion of the bottom of the bath. Solder D is then poured into the countersink around and over the drain-pipe and flange c to close the joint. The surface of the body of solder should still be below the level of the bottom of the bath. The plug-seat E, externally screwed with a fine thread adapted to cut its own way into the drain-pipe, is then screwed into the upper end of said drainpipe, until its preferably somewhat dished flangeebecomes firmly seated againstthe solder D, the surface of which should be roughly dressed to the contour of the under side ofsaid. flange. 'lhis flange 6 will wholly cover the solder, and, being suitably dressed or plated, make a neat finish.

The bottom of the plug-seat is grated, as-

IOC

without special dressing, possesses the advantage that the plug-seat may be readily removed by unscrewing whenever it becomes necessary to remove an obstruction from the drain-pipe by a force-pump or other means.

Although I prefer to use an externally screwthreaded plug-seat, it is not absolutely necessary to screw-thread it, because itmay be sufficiently secured by driving it into the upper end of the drain-pipe; but in all cases it is to be secured only in the drain-pipe so that it can be removed without disturbing the joint.

Having thus described my invention, what I 7 claim is- 1. The combination, substantially as before setforth,of the drain-pipe extending up through the bathbottom, and the plug-seat secured only in the said drain-pipe.

2. The combination, substantially as before set forth, of the drain-pipe, the mass of solder around its upper end for making a tight joint with the bottom of the bath or sink, and the flanged externally screw-threaded plug-seat screwed into said drain-pipe and covering the solder-joint with its flange.

3. The combination, substantially as before set forth, of the bath-b0t-tom,the countersunk lining thereof, the drain-pipe, the flanged thimble encircling and sustaining the drain-pipe, and the nut.

4. The combination, substantially as before set forth, of the bath-bottom, the countersunk lining thereof, the flanged thimble, the nut, the drain-pipe, and the solder above and around the flange of the thimble and the upper end of the drain-pipe.

5. The combination, substantially as before set forth, of the bath-bottom, the countersunk lining thereof, the flanged thimble, the nut, the drain-pipe, the mass of solder for making a tight joint, and the flanged externally-screwthreaded plug-seat.

In testimony whereof I affix my signature in presence of two witnesses.

WILLIAM RIGKETTS.
